Tila Tequila's Fiancee Casey Johnson Dead at 30

Casey Johnson was pronounced dead Monday morning in a Los Angeles area home, Usmagazine.com confirms. The heiress to the Johnson & Johnson fortune was 30 years old and recently made headlines as the apparent fiancee to reality star Tila Tequila.

"The Johnson family is mourning its tragic loss, and asks for privacy duringthis very difficult time," said a rep for the Johnson family on Monday evening.

"At this point, it appears to be a natural death," LAPD spokesperson Sara Faden tells Usmagazine.com. "There was no evidence of foul play. The coroner's office will now take over the investigation and conduct their toxicology screenings."

Johnson was mother to a three year-old girl, Ava. Johnson adopted Ava in Kazakhstan in 2007, but the little girl is now in the custody of Johnson's mother, Sale Johnson, in Manhattan.

Tila spoke to UsMagazine.com Dec. 22 about her relationship with Johnson. "She's just the most beautiful person I've ever met." The reality star said they got engaged "a couple weeks ago," and that she planned to adopt young Ava.
